Still Standing

Let me write this one more time that this place is 4,000 years old. The whole place and the houses are still intact. But how? This is because of the soil that is found in the Henan Province region. The soil is still solid and swamp, meaning there was no shrinkage or shifting took place during all these years and all of this contributed to their lastingness. Their ancestors knew what were they doing with the place and had the idea of how to make sure that this town stays the way it was back then.
